FreeBSD : lynx -- remote buffer overflow (c01170bf-4990-11da-a1b8-000854d03344)

High Nessus Plugin ID 21506


The remote FreeBSD host is missing one or more security-related updates.


Ulf Harnhammar reports :

When Lynx connects to an NNTP server to fetch information about the available articles in a newsgroup, it will call a function called HTrjis() with the information from certain article headers. The function adds missing ESC characters to certain data, to support Asian character sets. However, it does not check if it writes outside of the char array buf, and that causes a remote stack-based buffer overflow.


Update the affected packages.
